I would be unsurprised if the entire sushi-eating-capable* portion of humanity were able to consume the entire currently-living cetacean population in one busy afternoon and evening. I can not, at the time of writing, determine which result would cause me more sadness and general disappointment with humanity. Obviously, I know which result would surprise me more.
* Capability is determined as those with no known allergies with adequate income and also within a certain geographic proximity of a sushi-serving establishment and/or venue. (Ie. The Filet Strip Club and Sushi Bar in Courtsmouth, PA and that place in Albuquerque, NM where I went with my college girlfriend.)
